Question

A rectangular room is 2.5 m long, 3 m wide and 3.7m high. Find the total surface area of the four walls.

Answer 1

Answer:

40.70m²

Step-by-step explanation:

here l=2.5m

b=3m

h=3.7m

Now LSA(surface area of 4 walls.....Lateral Surface Area) = 2(lh+bh)

                                                                       = 2[(2.5*3.7)+(3*3.7)]m²

                                                                       = 2[9.25+11.1]m²

                                                                       = 2*20.35m² = 40.70m²
